路径地址转换

var flowFile = session.get();
if(flowFile != null) {
    try {
        var path = flowFile.getAttribute('要转换路径')
        var attrName = flowFile.getAttribute('存储属性名')
        flowFile = session.putAttribute(flowFile, attrName, path.replace(/\//g,"\\"))
        session.transfer(flowFile, REL_SUCCESS)
    } catch(e) {
        session.transfer(flowFile, REL_FAILURE)
    }
}
